ADS DM Client Can Not Connect to Samba

Thanks for the feedback. I'll summarize to this list my findings late 
tomorrow. I tried samba-3.0.6, 3.0.7, 3.0.8pre1, 3.1.0SVN - all failed to 
permit a Windows XPPro and Windows 2000Pro clients of an ADS domain to 
connect to a Samba server that is an ADS domain member. I tried this with 
Win2000 ADS as well as with Win2003 ADS. In all cases, when the client does a 
SessionSetupX using kerberos credentials the samba server reply causes the 
client to drop the connection. The client tries 3 times before giving up. It 
then presents the user with a logon box. No valid username/password pair will 
permit Samba server access.

Before reporting details I will verify on a newly installed environment.
